World Wide Web's Creator Wants Metaverse VR
Bloomberg Nate Lanxon May 11, 2022
World Wide Web creator and 2016 ACM A.M. Turing Award recipient Tim Berners-Lee expects virtual reality (VR) and metaverse-associated technologies to shape future online interaction. "People ask about virtual reality, and if the metaverse is going to be the whole future, and the answer is that it's going to be part of the future," he said. Berners-Lee said he envisions VR becoming a new form of media, one in which "you'll be able to sit between a movie and a VR world of that movie, for example." He is firmly opposed to the largest technology companies controlling much of their users' personal data.

Astronomers Image Massive Black Hole at Center of Our Galaxy
PC Magazine Michael Kan May 12, 2022
An international team of astronomers used supercomputers and computer algorithms to record the first image of Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy. The Event Horizon Telescope Collaboration (EHT) team employed eight radio telescopes to capture 3.5 petabytes of data including incomplete images of various parts of the black hole. Supercomputers processed and analyzed the data to produce composite images of Sagittarius A*. The EHT team said the image released on Thursday represents "an average of the different images the team extracted, finally revealing the giant lurking at the center of our galaxy for the first time."

Multi-Tasking Wearable Continuously Monitors Glucose, Alcohol, Lactate
UC San Diego News Center Liezel Labios May 9, 2022
University of California, San Diego (UCSD) engineers have created a prototype wearable device that can continuously track monitor glucose, alcohol, and lactate levels simultaneously. The device is applied to the skin of the upper arm via microneedles smaller than the width of a human hair, which detect biomolecules in interstitial fluid; it is attached to a case housing the device's electronics. When enzymes on the tips of the microneedles react with glucose, alcohol, and lactate in interstitial fluid, the wearable transmits analytical data wirelessly to a custom smartphone application. UCSD's Farshad Tehrani said, "With our wearable, people can see the interplay between their glucose spikes or dips with their diet, exercise, and drinking of alcoholic beverages. That could add to their quality of life as well."

NeuroMechFly: A Morphologically Realistic Biomechanical Model of a Fly
SciTechDaily May 11, 2022
Scientists at the Swiss Federal Institute of Technology in Lausanne, Switzerland (EPFL), have built the first accurate digital twin of a fly as a testbed for biomechanics and biorobotics. EPFL's Pavan Ramdya said the researchers based NeuroMechFly on computed tomography scans of a real fly of the species Drosophila melanogaster, and on insect limb movements measured by pose estimation software. The model features independent computational components that simulate different body parts, including a biomechanical exoskeleton with articulating elements, and neural network "controllers" with a motor output. The researchers initially made three-dimensional measurements of actual fly movements, then replayed those behaviors using NeuroMechFly's biomechanical exoskeleton within a physics-based simulation.

Gravity Signals Could Detect Earthquakes at the Speed of Light
Science Zack Savitsky May 11, 2022
Scientists at France's Cote d'Azur University have developed an algorithm to detect the backwash from speed-of-light gravitational waves radiating from temblors, as a method for identifying the magnitude of earthquakes faster. The Cote d'Azur team trained its algorithm on hundreds of thousands of simulated earthquakes, then tested it on data from Japan's 2011 Tohoku quake; the model overtook other state-of-the-art early warning systems by accurately predicting the quake's magnitude in about 50 seconds. The model, which the University of Florida’s Bernard Whiting calls "a proof of implementation," is set to be deployed in Japan.

AI System Learns Concepts Shared Across Video, Audio, Text
MIT News Adam Zewe May 4, 2022
An artificial intelligence technique developed by Massachusetts Institute of Technology (MIT) researchers can learn to represent data by capturing concepts shared between visual and audio modalities. The researchers' representation learning model can encode raw data like videos and corresponding text captions by retrieving observations about objects and actions in the video and mapping the data points in a grid. Similar data is clustered as single points in the grid, each of which is represented by an individual word. The model can use only 1,000 words to label vectors, choosing the word that best represents the data. Because the method uses a shared embedding space to encode two modalities together, the model can learn the relationship between them, such as video showing a person juggling and an audio recording of a person saying "juggling." The researchers found the model outperforms other machine learning methods at cross-modal retrieval tasks.

Tech Can Double Spectral Bandwidth in Some 5G Systems
Washington University in St. Louis McKelvey School of Engineering Brandie Jefferson May 11, 2022
Researchers at Washington University in St. Louis, Columbia University, and the City University of New York have implemented the first electromagnetic topological insulator on an integrated chip. The researchers applied time-modulation of transistor switches to support non-reciprocity—one-way propagation to electromagnetic (EM) waves—and topological insulation on a standard integrated circuit (IC). The technology can facilitate full-duplex communication and double spectral bandwidth, as well as supporting on-demand EM wave rerouting by reconfiguring individual unit-cells in the lattice. The researchers demonstrated the reconfigurable IC's utility for emerging 5G wireless applications like multi-antenna full-duplex wireless communications and multi-antenna impulse radar.

Costa Rica Declares Emergency in Ongoing Cyberattack
ABC News Javier Cordoba May 12, 2022
Costa Rica has declared a state of emergency after enduring a month of ransomware attacks that have hobbled critical systems. The siege began last month when Costa Rica's Finance Ministry reported that its tax collection, customs, and other systems were affected; the hackers also targeted the nation’s social security agency human resources system and its Labor Ministry. The Russian-speaking Conti gang took credit for the attack. Costa Rica’s emergency declaration describes the perpetrators as "cybercriminals" and "cyberterrorists." The U.S. State Department said the gang has orchestrated hundreds of ransomware attacks over the past two years, collectively targeting more than 1,000 victims and extorting them for more than $150 million as of January 2022.

We Got Closer to Mapping Nearly Every Single Cell Type in the Human Body
ScienceAlert Tessa Koumoundouros May 13, 2022
More than 2,300 researchers across 83 countries participated in four studies that collectively mapped over 1 million cells in 33 human organs. Explained Stanford University's Steve Quake, "What we've been able to do collectively here is help understand and interpret how different parts of the genome are used to define different cell types and create molecular definitions for all the different cell types we've studied collectively in these papers." The researchers applied new machine learning algorithms to extract critical molecular patterns, and used experimental processes to profile more cell types to help compile and search through the cell atlas. The datasets will enable scientists to chart links between cells for a whole-body map of biological processes and disease-inducing disruptions.

Virtual Tennis Racket Uses Air Jet to Recreate Feel of Hitting Ball
New Scientist Alex Wilkins May 10, 2022
Researchers at National Taiwan University, Canada's University of Waterloo, and the University of Maryland together developed the AirRacket, a virtual reality controller that emits bursts of compressed air to simulate a ball's impact in racket sports. The researchers designed the three-dimensionally-printed carbon-fiber AirRacket to incorporate cylinders of compressed air, while a perceptual illusion makes ball hits feel up to four times bigger than they actually are. David Swapp at the U.K.'s University College London said the air jet's sound and the force of the racket add to the illusion of playing tennis. Test participants said the controller made the game feel more immersive, while the impact sensations helped them target shots and sense how well they were hitting the ball.

U.S. Cities Back Off Banning Facial Recognition as Crime Rises
Reuters Paresh Dave May 12, 2022
Rising crime rates and stepped-up lobbying from developers are prompting U.S. cities to reconsider bans on facial recognition. Virginia in July will eliminate its prohibition of local police use of facial recognition just a year after its approval, while California and New Orleans could take similar actions soon. About two dozen U.S. state or local governments passed laws limiting the use of facial recognition technologies between 2019 and 2021. Although studies determined the technology was less effective in identifying Black people, research by the National Institute of Standards and Technology (NIST) has indicated industrywide progress in improving accuracy.

Europe Has a Plan to Fight Online Child Abuse; Critics Fear it may Erode Privacy
CNBC Ryan Browne May 11, 2022
The European Union (EU) has proposed legislation that would allow member states to ask courts to order companies like Meta and Apple to more aggressively police their online platforms for child abuse. A new EU Center on Child Sexual Abuse will enforce the legislation, and maintain a database of digital "indicators" of child sexual abuse content to match against material from relevant online services. The Electronic Frontier Foundation's Joe Mullin called the measure "incompatible with end-to-end encryption and with basic privacy rights," and warned it "would be a disaster for user privacy not just in the EU but throughout the world." Linus Neumann with German hacker collective Chaos Computer Club said criminals already employ distribution channels that avoid such scans, and will easily evade them in the future.
